Corps officials earlier announced a delay in openings until they could better assess funding limitations for the 2013 recreation season.

Responding to public demand, the Corps has fully opened boat ramps at nine locations along the river.

However, because of funding constraints, they canceled service contracts for the other parks along the navigation system as well as the hiring of summer park rangers.

Commercial services will be available at the marinas at Three Forks and Applegate Cove.

The closings impact only recreation areas along the navigation system and do not impact other Tulsa District lakes and their campgrounds, providing camping alternatives at other Corps recreation areas at nearby lakes, according to a Corps news release. The closest alternative for campgrounds at R.S. Kerr and Webbers Falls is Tenkiller Lake at 20-30 miles. Fort Gibson is the closest alternative for Chouteau and Newt Graham at 15 miles.

Campers who have made summer reservations at Applegate Cove, Short Mountain Cove, and Cowlington Point campgrounds at R.S. Kerr can call 877-444-6777 for a full refund or to rebook at a campground that is open.

• Spaniard Creek Day Use Area and Highway 10 Landing will be open for boat launching only.

Services such as mowing, cleaning and restroom availability may not be provided if previously available at these ramps, the release states.

In Arkansas, the Little Rock District of the Corps reported there would be no changes to the shortened seasons put in place last year.

Area sites impacted include Ozark, where campsites were closed at Citadel Bluff and River Ridge, and where the day use area at Reed Mountain was closed. The Corps ordered the boat ramps closed at Citadel Bluff and Reed Mountain.

Altogether, the Little Rock office proposed changing recreation operations at 29 parks, including closing 13 campgrounds, four partial campgrounds, four day use areas, one partial day use area, and 10 boat ramps. Officials also shortened the recreation season at many additional parks.

Other park adjustments made last year and likely to continue this year, include reducing the frequency of trash pickup, cleaning and mowing, as well as reduced maintenance response time and fewer temporary park rangers, law enforcement agreements and contract park attendants.
